PLANO - Frito-Lay announced today that it's voluntarily recalling 41 cases of mispackaged potato chips that could pose a risk to people with milk allergies.

The recall involves almost 2,500 11/2-ounce bags labeled Lay's Classic Potato Chips available in North Texas vending machines. The bags may contain Lay's Cheddar & Sour Cream Flavored Potato Chips. The Plano-based snack maker says that's because of an error that occurred in a production line.

The affected bags have a freshness date of February 12th located on the upper right hand side of the package with an 11 digit code number beneath the date (12923230985). The bags are time stamped between 06:00 and 08:00.

Consumers who buy the affected bags can contact Frito-Lay Consumer Affairs at 1-800-352-4477.
